charging. Wipe off any battery uid that may have
come in contact with the clamps to prevent corrosion.
● Occasionally cleaning the case of the charger with a
soft cloth keeps the nish shiny and help prevent
corrosion.
● Coil the input and output cords neatly when storing
the charger. This helps prevent accidental damage to
the cords and charger.
● Store the charger unplugged from the AC power
outlet in an upright position.
● Store inside, in a cool, dry place. Do not store the
clamps on the handle, clipped together, on or around
metal, or clipped to the cables.

Problem Possible Cause Solution
Battery clamps do not spark when touched
together.
The charger is equipped with an auto-start
feature. It will not supply current to the battery
clamps until a battery is properly connected.
The clamps will not spark if touched together.
No problem; this is a normal condition.
The charger will not turn on when properly
connected.
AC outlet is dead. Check for open fuse or circuit breaker
supplying AC outlet.
Poor electrical connection. Check power cord and extension cord for the
loose tting plug.
Short or no start cycle when starting engine. No power at receptacle. Check for open fuse or circuit breaker
supplying AC outlet.
AC cord and/or extension cord is loose. Check power cord and extension cord for the
loose tting plug.
The clamps are not making a good
connection.
Check for poor connection at battery and
frame.
Failure to wait 3 minutes (180 seconds)
between cranks.
Wait 3 minutes of rest time before the next
crank to allow the battery and charger to cool
down.
The battery may be severely discharged.

10A BOOST
On a severely discharged battery, use the 10A
Boost setting for few minutes to help assist in
cranking.
The battery is drawing more than the Engine
Start Rate.
Crank time varies with the amount of current
drawn. If the cranking draws more than the
Engine Start Rate, crank time may be less
than 3 seconds.
The charger may be overheated. The thermal protector may have tripped and
needs a little longer to close. Make sure that
the charger vents are not blocked. Wait and
try again.

RED LED
The red LED is lit.
The battery voltage is still below 10 V after 2
hours of charging. In maintain mode, the
output current is more than 1.5A for 12 hours.
The battery may be defective. Make sure that
there are no loads on the battery. If there are,
remove them. If there is none, have the
battery checked or replaced.
Desulfation was unsuccessful. The battery may be defective. Have battery
checked or replaced.

The battery may be overheated. If so, allow
the battery to cool. The battery may be too
large or have a short circuit. Have battery
checked or replaced.
The battery’s initial voltage is below 12.2 V
and the total input is less than 1.5 Ah.
The battery capacity is too low, or the battery
is too old. Have it checked or replaced.
The battery voltage drops to below 12.2 V in
Maintain Mode.
The battery won’t hold a charge. May be
caused by a drain on the battery or the battery
